Sarah, my good friend's young daughter gives a touching farewell, expresses thanks and love for her doggie who today crossed the Rainbow Bridge until they meet again. Dear Rocky, Writing this has been the hardest thing I've had to do. You have always been my favorite hello and my hardest goodbye. I want to thank you for being my best friend for the past 6 years. No matter what life has thrown, you have always been my shoulder to cry on or my partner to run around with.
